Japanese Dongcao Chemical (Guangzhou) Chemical Wastewater Technical Renovation Project

Technical Renovation Project for Production Wastewater of Japanese Dongcao Chemical (Guangzhou) Co., Ltd. (300m ³/d)

Project Name: Production Wastewater Technical Renovation Project

Processing technology: FCM-IV catalytic self electrolysis

Construction time: 2019

Processing effect: The company mainly produces polyvinyl chloride resin. There is currently one set of production wastewater treatment system, which mainly degrades through a biochemical system

Its CODcr. Due to the technological transformation of the production process, approximately 300m3/d of toxic benzene based pollutants and copper and chromium ion pollutants are newly generated. The biochemical department

Low efficiency in management. The CODcr of this wastewater is 2000-8000mg/L, and the original biochemical process cannot adapt to this type of production wastewater. Our company has adopted FCM-IV

After pretreatment with catalytic self electrolysis technology, the effluent is clear, with CODcr stable at 800-1000mg/L and significantly improved biodegradability. Subsequently, it undergoes primary treatment

The effluent is treated by a chemical system and meets the requirements of the local discharge standards (DB44/26-2001) in Guangdong Province.
